Dr. Ramonna I. Kosheleva is a researcher in materials science and surface phenomena working at the Department of Chemistry, Democritus University of Thrace (Greece). Her research focuses on adsorption processes, nanoporous materials, and advanced characterization techniques for functional adsorbents. She obtained her Ph.D. in Chemistry from the Aristotle University of Thessaloniki with a dissertation on the effect of rotational fields on vapor and gas storage in nanoporous materials. Her work integrates surface chemistry, interfacial phenomena, and material characterization methods to understand adsorption mechanisms and develop materials for environmental and energy applications, including water purification, gas storage, nanobubbles, and graphene-based adsorbents.
